An imaging device includes an image sensor, a fill light lamp, and a controller configured to obtain an automatic exposure parameter of the image sensor, and control an illumination intensity of the fill light lamp based on the automatic exposure parameter by adjusting the illumination intensity to a preset value when the automatic exposure parameter falls within an automatic exposure parameter range.

Provided is a light emission control apparatus, a light emission control method, a light emission apparatus, and an imaging apparatus that make it possible to emit AF assist light with a more appropriate amount of light. A light emission unit is capable of emitting AF (Auto Focus) assist light when capturing a static image and illumination light when capturing a moving image. A light-amount setting unit sets the amount of AF assist light to a light emission control unit, the light amount being obtained in accordance with a distance to an object to be focused on or specification by a user, and the light emission control unit controls light emission of the AF assist light in accordance with the setting.

To increase the accuracy of adjusting the main light emission. An amount of main light emission is adjusted on the basis of an estimated pre-light-emitted subject distance or information corresponding to the estimated pre-light-emitted subject distance and an estimated lens-focused subject distance. The estimated pre-light-emitted subject distance and the information corresponding to the estimated pre-light-emitted subject distance are obtained by pre-light-emission processing. The estimated lens-focused subject distance is obtained from focus information through a lens. In a case of bounce light emission, in a case where the estimated pre-light-emitted subject distance is smaller than the estimated lens-focused subject distance, a distance made closer to the estimated lens-focused subject distance from the estimated pre-light-emitted subject distance by a predetermined amount is set as an estimated subject distance for adjusting the main light emission.

With a pre-light emission quantity adjusted to an appropriate value, the accuracy of light control for main light emission can be enhanced. A first pre-light emission quantity is obtained with no use of distance information. An appropriate light emission quantity is obtained with use of distance information, and a second pre-light emission quantity is obtained by decreasing the appropriate light emission quantity by a predetermined quantity according to a photometric wave detection capacity. A final pre-light emission quantity is obtained by mixing the first pre-light emission quantity and the second pre-light emission quantity, at a ratio corresponding to the accuracy of the distance information used to obtain the appropriate light emission quantity.
